Abstract

L’invention concerne un arbre de liaison (200) d’un corps haute pression de turbomachine, ledit arbre de liaison (200) étant configuré pour coupler en rotation un module rotatif, ledit arbre de liaison (200) comportant un corps (220) présentant au niveau de l’une de ses extrémités une bride annulaire (210) configurée pour être couplée au module rotatif (100), ledit arbre de liaison (200) étant caractérisé en ce qu’il comporte une première gorge circonférentielle (230) ménagées au niveau de la paroi du corps (220) dans une région voisine de ladite bride annulaire (210) et s’étendant au moins partiellement sur une portion circonférentielle de la paroi du corps (220). Figure de l’abrégé : Figure 1.The invention relates to a connecting shaft (200) of a turbomachine high-pressure body, said connecting shaft (200) being configured to couple in rotation a rotary module, said connecting shaft (200) comprising a body (220) having at one of its ends an annular flange (210) configured to be coupled to the rotary module (100), said connecting shaft (200) being characterized in that it comprises a first circumferential groove (230) provided at the body wall (220) in a region adjacent to said annular flange (210) and extending at least partially over a circumferential portion of the body wall (220). Abstract Figure: Figure 1.
